FOOD-SLICING MACHINE.

Application filed March 18, 1913. Serial No. 755,432.

To all to]: om it may concern Be it known that I, HANs P. HOLM, acitizen of the United States, residing at Davenport. in the county ofScott and State of Iowa, have invented certain new and use- -fulImprovements in. Food-Slicing Machines, of which the following is aspecification.

My present in ention relates generally to the class of machinesforcutting. slicing or ch pping meats or cther food materials.

The primary object of my invention is to provide a machine ofthis'character wherein the meat or other food materials to be operatedupon is presented tothe cutting or slicing mechanism pcsitivelv and withthe desired regularity and rapidity.

A further object of my invention contemplates the provisicn of simpleand efficient means whereby the meat or food operated upon is preventedfrom adhering to the knives or cutters, such means alsoserving asguideways for the cutting blades.

A still further object of my invention resides in the provision ofsuitable means whereby uniform lateral adjustment of the cutting bladesis permitted.

A further object of my invention is to provide a machine of thischaracter, capable of slicing any manner of food or food materialWlIQtSCGYBI the food being brought to, through and from the slicing orcutting mechanism by its own weight or by gravity, a feature, as far asknown to theinventor no other food slicing machine employs.

A still further object of the invention is to provide means, arrangedwithinthe machine, whereby the size, thickness and quantity of foodslices may be. varied as desired or as occasion demands.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the following specification, and then more particularlypointed out in the claims which are appended hereto and form a part ofthis application;

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a front elevation of a machine construeted accordance with mySpecification of Letters Patent.

to be hereinafter fully described.

invention. Fig. 2 is a side elevation. Fig. 3 is a section on line 3-3of Fig. 1. Fig.4 IS a section on line l-4 of Fig. 3. Fig. 5 is a detailelevation of the blade adi'isting mechanism. Fig. 6 is a detailelevation of the blades. with the adjusting mechanism shown in section.Fig. 7 is a detail view of one of the guide pins. Fig. 8 is a modifledform of shaft bearing. Fig. 9 is a detail perspective view of one of thes acing brackets, F 10 illustrates a modified form of blade adiustingmechanism. and Fig. 11 is a modified form of blade cleaning device.

Proceeding now to the descripti n of the drawings wherein is illustratedthe preferred form of my inventi n the numeral 1 designates the fourvertically extending a pair of intermediate vertical angle-braces 5extending throughout the entire length of the frame and projecting as at6. ab ve the top thereof. An intermediate laterally extending brace iron7 connects the rear ir ns labout midway the length thereof. while braces8 are provided, in alinement with the brace 7 upon each side of theframe.

Two forward or front braces 9 and 10. corresponding in size and shape tothe braces 8. are disposed, one brace 9 upon the inner face of the frontiron 1, and slightly he neath the other brace 10 which is secured uponthe upper face thereof for a purpose The upper extremity of thefranie isprovided with brace ircns 11, disposed (preferably) in a like manner tothe lower irons 3 of the frame, the said irons 11 supporting the top12of the frame which is secured thereto in any suitable manner. Sideplates or pieces 13 and rear plates 14 are detachably secured totheframe irons in any suitable manner to permit'tlieir removal, shouldoccasion zlemand, for cleaning or repairing the interior of the machine.

The rear vertically extending angle-irons 1 projectabove the frame as at15 and are connected to the intermediate vertically extending irons 5through the medium of connecting bars 16, vhile the irons 5 are bracedby means of bars 17 depending at an angle from the top thereof to theforward extremity of certain of the upper irons l1.

A shaft 18 (square in cross section throughout thegreater portion of itslength) is jdurnaled Within the upper extremity of the pcrtion 15 of theiron 1, Which shaft is provided with pulleys 19 and 20 loosely mountedthereon, for the purpose of impart ing motion to other machines ormechanism (not shown) which may be secured upon. the

top of the frame or employed in connection with the machine embodyingthis invention. Another pulley 21 is keyed or otherwise secured upon oneend of the shaft 18 and connected to a third or double pulley 22,mounted upona stud shaft 23, through the medium of a belt or cord 24, bymeans of which motion is imparted to the said shaft 18'. A motor of anytype may be connected, if desired, to the double pulley by any suitablemeans, thereby imparting motion to the shaft 23. A gear wheel 25 ismounted upon one end of the stud shaft 23, the said gear meshing with apinion 26 secured upon one end of the main shaft 27 of the machine.

- Bearings 28are detachably secured to the intermediate verticallyextending irons 5 of the machine within which, the main shaft 27 isslidably journaled, thus Permitting an entire removal of the said shaft,or should occasion demand allowing the same to be laterallyslid withinits bearing for disengaging the pinion 26 and the gear Wheel 25, whichdisengagement would permit independent operation of the shaft 18 and itsaccessories without operating the slicing mechanism controlled by therotation of the main shaft 27. With the exception of the shaftextremities, the said shaft is preferably polygonal or square in crosssection, for the purpose of rotating a plurality of circular blades 'orcutting knives 29-, loosely mounted thereupon and slidable thereon,

the said knives being provided with collars- 30 provided with openings31 through which the said shaft extends.

A slide 32 having sides extending throughout its length, ispivotallymounted as at 33 to the forWardangle-irons 1 of the machine for normallyclos ng the upper front portion thereof. the said slide being held insuch closed position through the med um of suitable latch mechanism 34.A hand lever 35 is pivotallv secured as at 36 upon one side of the slide32.. the sa d lever being provided with a plurality of spaced apartnotches 37 adapted to engage the upper cross iron 10 of theframe forhold ng or supporting the slide 32 upon an incline, or as is clearlyshown by the dotted lines in Fig. 3 of the drawings. A door 88 hingedlysecured as at 41 to the rear intermediate angle-iron 7, and extends uponan angle within the interior of the frame to the floor 4 thereof, thesaid slide-way 40 receiving the material operated upon after the samehas left the guide-way 32 above mentioned. A tray 42 is hingedlyconnected as at 43 to one of the angle-irons 3, the said tray whenclosed by the latch 44 provided for that purpose, creating a door orclosure for the lower front portion of the machine. and normallyengaging the cross iron 9. which limits the inward movement of the saidtray. The tray when opened as indicated by the dotted lines in the saidFig. 3 forms a receptacle for the material acted upon as the same flowsor falls from the slide 40 of the machine.

The means employed for adjusting the blades 29 and for guiding the sameduring the r rotary mo 'ementcomprises a substantially U-shaped bracket45 detachably secured in any suitable manner to cross bars 46 extendingupon the interior of the machine from the rear vertically extendingirons 1 to the intermediate irons 5. A slotted plate 47 is adiustablvsecured to the bracket 45 through the medium of a pair of transverselyextending pins or bolts 4-8, the said adiustment being controlled by themanipulation of the nuts 49 provided for that purpose upon. the saidbolts 48. Lazy-' of a hand lever 52 pivotallvsecured as at 53 to thesaid tongs. One of the said tongs 50 is fixedly secured to the plate 47by means of a link 54 permanently secured as at 55 to the said plate. Bythis construction it will be seen that the operation of the s aid lever52 will cause the tongs to open and close as desired. The said tongs arepreferably sem -circular in form and extend,asis shown in Fig. 6 of thedrawings so as to partially surround the blades 29. The extremities ofthe tongs a e provided with adiustable pins 56 provided with bifurcatedends 57 within which the pe iphery of the blades 25) normally rotate. Byreason of the said b furcat ons. the lateral mo ement of the blades 29upon the shaft 27 is controlled by the movement of the tongs 50, thesaid pins 56 simultaneously moving the blades acnovel and peculiarconstruction will also serve as a cleaning device for. the blades andwill prevent adhering of the meat or other'material thereto inoperation.

Referring now -to the modification shown in Fig. 8 the main shaft (notshown) is mounted between blocks 58, one of which is ad ustably securedto the angle-iron 59 by means of a plate 60 held in proper place throughthe medium of screw bolts 61. This form of bearing will greatlyfacilitate the removal of the main shaft should occasion demand.

Passing on to the description and the modification'shown in Fig. 11, thenumeral 66 designates a revoluble shaft, square in cross section, theends being journaled in .1 the machine sides or frame as is clearlyshown. A hand lever 67 is secured to the said shaft 66 for swinging thefingers 68 out of and into engagement with the circular blades OftllBmachine, the said fingers being slidably mounted upon the said shaft I66 so as to permit adjustment as required,

one finger upon each side and in engagement with the said circularblades. arrangement of the fingers will permit a thorough cleaning ofthe blades during the operation of the machine, and will allow anynumber of blades tobe employed and Y cleaned in the manner above setforth. By

operating the lever 67 and removing a pin 69 for normally holding thesaid shaft against rotation, the shaft may be partially rotated forswinging the fingers out of en gagement with the said blades, whereuponthe cleaning mechanism disclosed as a preferred form may be employed.

When it is desired that meat or other material should be sliced verythin, and the lazy-tong mechanism is incapable of answering the purposesof bringing the circular knives closely together, the said lazytongmechanism is then raised out of serv ice, by operating the nuts 49 and aplurality of U-shaped members or spacing brackets 62 are fitted upon theshaft between the knives 63, thereby spacing the same uniformly. Whenproperly spaced, the knives 63 areheld in position by the nut Gel.threaded upon one end of the shaft 65, the adjusting of the said nutuntil it tightly engages a washer 65 causing the latter to tightlyengage the end spacing bracket 62 for preventing lateral movement of theknives upon the said shaft. The size of the members 62 may be varied,thus reducing or increasing the distance between the knives or blades ofthe shaft and producing a machine capable of slicing the material to anydegree of thickness or thinness desired.

After bringing the knives closely to- This gether as above describedthebracket 62 is placed between the last knife on the shaft and the washerwhereby the turning of the terial acted upon is first placed upon theslide-way 32, the said way having been inclined through the operation ofthe lever 35, and the door 38 having been raised or opened to permit theinsertion of the said material. By reason of the incline surface of thesaid slide 32 the meat is forced into engagement with the knives 29, therotatiori'oi the latter, whichis downward on the food, not only cuttingor slicing the meat but forcing the same down upon the oppositelyinclined slide-way 40 where it is carried by reason ofthe inclinedsurface down to the tray 42 for subsequent removal.

It will be seen from the above taken in connection with the accompanyingdrawings that the operation or manipulation of the lever 52 will slidethe blades 29 upon the main shaft of the machine as desired; that theoperation of the nuts 49 will regulate notches 37 provided within thehand lever 35 will permit an adjustment of the slideway 32 in relationto the blades 29, as desired.

It will be understood that the above description and accompanyingdrawings coinprehend only the general and preferred embodiment of myinvention; that the power applied to the machine may be derivedv fromany source whatsoever; and that various minor changes in the details ofconstruction, proportion and arrangement 'of the. partsinay be madewithin the scope of the appended claims and without sacr ficing any ofthe advantages of my invention.
